cin with weakly acidic catalyses or with bis(tri-n-butyltin)oxide and bromine leads to the formation of a lactone in high yield via a stereocontrolled tertiary α-ketol rearrangement. This product was chemically related to spectionic acid which in turn was transformed into 5-deoxy-α-D-isosacharino-1,4-lactone of known absolute configuration. The stereochemical identity of this acid is thus secured.
